There has been a lot of emphasis on how Irish this film is, but that doesn’t mean Martin McDonagh meant to exaggerate. The critically acclaimed writer-director apparently drew a line with the film’s soundtrack where things needed to be a little less Irish. According to the film’s composer, Carter Burwell, he was specifically told why, despite the overwhelmingly Irish setting, cast and story, traditional Irish music wouldn’t work for The Banshees of Inisherin.
During an interview with Variety, he said McDonagh told him “I hate that Deedle-Dee, old Irish film score” and instead requested something more contemporary that would fit the characters on screen. In another piece by The Wrap, he added more context, saying, “It definitely struck a chord, so I never brought that up again. But it wasn’t obvious what else it was supposed to be, so I waited until I saw some of the footage before I even started thinking about it again.”
